Hi! Sorry for opening two posts in a row, but I’m curious if anyone has experienced battery issues with their notebook after upgrading from Windows 8.1 to 10. I’ve noticed a big difference—my battery used to last nearly five hours while watching movies at 1080p with airplane mode off and a bright screen, but now it only lasts a couple of hours under the same settings. I was also using energy-saving software on my Lenovo Y50-70 before, and I wonder if others noticed similar changes.
I haven't noticed any variations in battery endurance between 8.1 and 10. On my tablet, the battery lasts around seven hours during video streaming, similar to its performance under Windows 8.1. The updated power-saving feature works well, and turning off Wi-Fi when the device is idle makes a big difference on a tablet.
In my situation I’m certain I didn’t change anything because I verified everything. Sending data with Win 10 seems highly unlikely since my Wi-Fi was off. Regarding CPU usage, it’s possible the operating system itself is causing the issue rather than your software. If the same tasks produce different results across two completely different OSes under identical conditions, the problem likely lies with the OS. If your CPU usage was significantly higher in Win 10 without any adjustments, it probably isn’t a hardware fault but an OS-related one. Concerning the battery energy saver on Win 10 (unchecked), it doesn’t seem to affect performance even when using download mode—so it’s not acting as a contrasting software program.
Ensure the latest Intel integrated drivers are installed. Windows 10 operates continuously in Balance mode unless otherwise configured. 'Eco' mode is a recent addition to Windows 10, distinct from Power Saving. It restricts background processes and fine-tunes hardware settings for greater energy efficiency, though Microsoft hasn't shared further specifics. By default, it activates when the battery drops to 20%, but you can adjust the behavior. My assumption is that this change applies to Intel Y/U/M series CPUs and Intel Atoms (similar in AMD), where Power Saver mode is too strong and disrupts user experience. This is just my interpretation. You can choose to enable it according to your preference.
